Heh. If it is massless and moves at "c", it is a photon. Call it a wave or particle as observations dictate.

 

AM radio "waves" are photons. Same with visible light and X-ray, to cover a fair chunk of the "photonic spectrum" - even though tend to think of photons as limited to the visble light segment of the EM radiation spectrum.
